Smart-Money Mirror v1 — executable strategy
First-track paper deployment that mirrors top-N positions across our 7 tracked managers (Druckenmiller, Marathon, Berkshire, Russo, Akre, Tiger Global, Tepper). Deploys NOW because the
/investing:smart-money-watchskill is already built and the 2026 Q1 13F backfill is on disk. The lag (45-90 days from quarter-end disclosure) is the cost; the access to their selection IS the alpha. This strategy is intentionally simple — that's the point.
Honest framing
This is NOT a strategy that out-thinks Druckenmiller, Berkshire, or Tiger Global. It IS a strategy that copies positive-sum managers who already out-think markets, with a 45-90 day disclosure lag. The 13F filing window is what we pay for the read. The selection itself — what these allocators chose to size up on, after they did the work we cannot replicate — is the alpha.
Tracked manager set (7, Pabrai excluded per 13F lookup failure in 2026-05-17 backfill):
| Manager | Style | Source |
|---|---|---|
| Duquesne Family Office (Druckenmiller) | macro long-biased | CIK 0001536411 |
| Berkshire Hathaway | long-only quality | CIK 0001067983 |
| Tiger Global Management | growth/tech long | CIK 0001167483 |
| Appaloosa LP (Tepper) | macro long-biased | CIK 0001656456 |
| Gardner Russo & Quinn (Tom Russo) | long-only compounder | CIK 0000860643 |
| Akre Capital Management | long-only compounder | CIK 0001112520 |
| Marathon Asset Management LLP | capital-cycle | CIK 0001040592 |
Selection rules (deterministic, not narrative)
1. Persistent darlings (high-confidence core)
Definition: any name in top-10 across 3+ managers AND held for 2+ consecutive quarters.
Per the [[01-projects/investing/anchors/smart-money/2026-05-17-aggregate-2yr-backfill-summary]] persistent-darlings table:
| Ticker | Issuer | # Managers in top-10 | Managers |
|---|---|---|---|
| MSFT | MICROSOFT CORP | 3 | Tepper, Druckenmiller, Tiger Global |
| AMZN | AMAZON COM INC | 3 | Tepper, Druckenmiller, Tiger Global |
| GOOGL | ALPHABET INC | 3 | Tepper, Berkshire, Tiger Global |
| TSM | TAIWAN SEMICONDUCTOR MFG LTD | 3 | Tepper, Druckenmiller, Tiger Global |
Allocation: 0.5R each = $2,500 × 4 = $10,000.
(Original draft was 1R each = $20k on persistent alone, which consumed the full initial budget. Re-spec to 0.5R each leaves room for signal-track adds + cash reserve.)
2. Recent multi-manager additions (signal-track)
Definition: any name where 2+ managers added or significantly increased same quarter, AND the add was within the last 2 quarters (currently 2025 Q4 + 2026 Q1).
Per the aggregate brief's collective-additions table for 2026 Q1:
| Quarter | Ticker | Issuer | Managers | Already covered? |
|---|---|---|---|---|
| 2026Q1 | SNDK | SANDISK CORP (new) | Tepper, Druckenmiller | NO — add 0.5R |
| 2026Q1 | INTC | INTEL CORP (new) | Druckenmiller, Tiger Global | NO — add 0.5R |
| 2026Q1 | AMZN | AMAZON COM INC (increased) | Tepper, Druckenmiller | YES — already in persistent darlings |
Allocation: 0.5R each = $2,500 × 2 = $5,000.
(SNDK + INTC also overlap with the memory-cycle v1.1 thesis basket. That overlap is deliberate — when two independent signals — a structural thesis AND multi-manager smart-money corroboration — point at the same name, both signals get their own paper trade. Position-tracking ledgers stay distinct per strategy.)
3. Total initial deploy + cash reserve
| Bucket | Sizing | $ |
|---|---|---|
| Persistent darlings (MSFT + AMZN + GOOGL + TSM at 0.5R each) | 2.0R | $10,000 |
| Signal-track adds (SNDK + INTC at 0.5R each) | 1.0R | $5,000 |
| Total initial deploy | 3.0R | $15,000 |
| Cash reserve (for next quarter's incremental adds when 2026 Q2 13Fs land mid-Aug) | — | $5,000 |
| Strategy notional cap (founder-greenlit) | $20,000 |
Initial ticker basket (this strategy, founder click-through gates)
| Ticker | Role | Tranche 1 (initial) | Max in v1 | Signal source |
|---|---|---|---|---|
| MSFT | Persistent darling (hyperscaler) | 0.5R = $2,500 | 1R | Top-10 in 3 managers (Tepper, Druckenmiller, Tiger Global) for 2+ quarters |
| AMZN | Persistent darling (hyperscaler) | 0.5R = $2,500 | 1R | Top-10 in 3 managers (Tepper, Druckenmiller, Tiger Global) for 2+ quarters |
| GOOGL | Persistent darling (hyperscaler) | 0.5R = $2,500 | 1R | Top-10 in 3 managers (Tepper, Berkshire, Tiger Global) for 2+ quarters |
| TSM | Persistent darling (ai-infra-chips) | 0.5R = $2,500 | 1R | Top-10 in 3 managers (Tepper, Druckenmiller, Tiger Global) for 2+ quarters |
| SNDK | 2026 Q1 multi-manager entry (memory) | 0.5R = $2,500 | 1R | New positions opened by Druckenmiller + Tepper in 2026 Q1 |
| INTC | 2026 Q1 multi-manager entry (broad semi) | 0.5R = $2,500 | 1R | New positions opened by Druckenmiller + Tiger Global in 2026 Q1 |
Total initial: 3.0R = $15,000. Cash reserve: $5,000 for Q2 adds.
Watchlist deltas — proposed for 2026 Q2 13F rebalance (added 2026-05-18, founder-approved)
Per Wright-synthesis concept article 2026-05-18 ([[../../../06-reference/concepts/2026-05-18-wright-agentic-capital-stack-vs-rdco-synthesis.md]]) — 3 named adds + 1 trigger-rule change. These do NOT deploy today; they take effect at the next 13F rebalance (mid-Aug 2026):
| Ticker | Rule change | Rationale |
|---|---|---|
| AMKR | Upgrade trigger: any 1-manager top-10 = ADD (was: 2-manager threshold) | OSAT / advanced-packaging picks-and-shovels under Wright's slate-fund-underwriter layer. CoWoS capacity is the bottleneck on AI accelerator supply; AMKR is one of the few names that ALSO benefits if slate funds emerge as Apollo-class capital flows into agent firms (the financing layer needs the same fab capacity to scale). 1-manager threshold reflects "thinner signal but stronger structural alignment than the 2-mgr names." |
| SHOP | Add on 2-mgr signal-track rule (standard signal-track threshold) | Programmatic working-capital incumbent (Shopify Capital deployed $2B+ to merchants 2016-2021). Wright explicitly names Shopify as the most-likely incumbent to "ship the feature" — extending its working-capital product to agent firms as the agent-economy emerges. The 2-mgr threshold keeps standard signal-track discipline. |
| COIN + CRCL | New "tokenization-rails" sub-bucket — both names track Wright's settlement-layer thesis (stages 3-5 of his capital stack). Trigger: either name appears in top-10 of any 1 tracked manager + Q-over-Q tokenization-onchain volume continues to >2x | Tokenization is the SETTLEMENT layer under stages 3-5 of Wright's stack. RWA market $25B+ onchain by early 2026 (~4x YoY). COIN (exchange / custody) + CRCL (USDC issuer) are the public-equity proxies for this layer. Adding as a sub-bucket so the sizing logic stays distinct from persistent darlings + signal-track. |
Explicit non-adds (documented 2026-05-18 to prevent re-litigation):
- Apollo / Ares — they are the BUYER class in Wright's frame, not the issuer/asset. Investing in Apollo doesn't capture the agentic capital markets thesis cleanly; we'd be paying for Apollo's existing private-credit franchise, not the agent-firm exposure.
- Sierra / Harvey — Wright's exemplar agent firms ($15B / $11B private valuations) but PRIVATE; can't be paper-traded on Alpaca. Move to private-market-watchlist if/when an SPV becomes available; otherwise watchlist-only for IPO timing.
Action timing: Ray drafts 2026 Q2 rebalance proposal post-2026-08-14 13F filings, surfaces via channel + /decisions/ page, founder approves the batch, Ray executes per the standard quarterly cadence below.
Rebalance rules (mechanical, quarterly)
Trigger window: 13F filing window (~45-60 days after quarter end). Calendar dates:
| Quarter end | 13F filing deadline | Strategy rebalance window |
|---|---|---|
| March 31 | May 15 | mid-May |
| June 30 | August 14 | mid-Aug |
| September 30 | November 14 | mid-Nov |
| December 31 | February 14 | mid-Feb |
Rebalance actions (mechanical, executed by Ray after quarterly review with founder):
| Trigger | Action |
|---|---|
| NEW multi-manager addition appears (2+ tracked managers add or significantly increase same name same quarter) AND name not already at v1 cap | Add 0.5R to that name (cap at 1R per name in this strategy) |
| 2+ tracked managers EXIT same name same quarter | Close that position entirely. This is the only mechanical exit rule. |
| Persistent darling status BREAKS — drops from 3+ managers to 2 managers in top-10 | Trim to 0.5R (or hold if already at 0.5R) |
| Persistent darling status BREAKS further — drops to 1 manager | Close position entirely |
| Existing position remains held by signal source (no change in manager count or direction) | Hold; no action |
| Cash reserve allows new add but no qualifying new signal | Hold cash; do not force-deploy |
Quarterly review with founder before executing trims/exits. Ray drafts the rebalance proposal post-13F-filing window, surfaces via channel or /decisions/ page, founder approves the batch, Ray executes.
NO price-based exits
Same lesson as memory-cycle v1.1: drawdowns do not trigger sells. Only multi-manager exits trigger sells. A 30% drawdown on a persistent darling that 3 managers still hold = HOLD. A flat position that 2+ managers exited last quarter = CLOSE.
This is the strategy's core discipline: the mirror is the signal. If the people we're mirroring still hold it, so do we. If they bail, so do we (with a 45-90 day lag). Price action between disclosure windows is noise.
The single override: founder kill-switch via channel ("pause smart-money", "halt mirror") = close all immediately.

Quarterly review template
Filed to ~/rdco-vault/01-projects/investing/strategies/reviews/<YYYY-Q[N]>-smart-money-mirror-v1.md after each 13F window.
Checks each quarter:
- New collective additions — any new 2+ tracked-manager same-quarter adds? List ticker, managers, and proposed add size.
- New collective exits — any 2+ tracked-manager same-quarter exits on names we hold? List ticker, managers, proposed close.
- Persistence delta on darlings — for each of MSFT / AMZN / GOOGL / TSM, count current top-10 managers. Flag any drop from 3+ → 2 (trim) or → 1 (close).
- Cash reserve state — current cash, proposed deployment if any qualifying signal exists.
- Total P/L vs SPY benchmark — strategy total return since inception vs SPY total return same window. The mirror should be at least beating SPY net of disclosure lag; if it isn't after 4+ quarters, the strategy needs revisit.
- Anomalies / single-manager rotation noise — flag any names where 1 tracked manager moved hard but no second-manager confirmation. NOT a trade signal in v1; noted for future-quarter watch.
Disqualifying conditions (strategy-archive triggers)
The strategy retires (not just any single position closes) under these conditions:
| Trigger | Severity | Action |
|---|---|---|
| Strategy underperforms SPY total return by >15pp over 4+ consecutive quarters | High | Founder review; consider archive |
| 4+ tracked managers stop filing 13Fs (regulatory shift, restructure, wind-down) | High | Strategy archives — too few signal sources |
| Smart-money-watch skill breaks and isn't fixed within 2 quarters | Medium | Strategy pauses pending tooling repair |
| Founder kill-switch ("retire mirror" / "archive smart-money-mirror") | n/a | Immediate close, post-mortem filed |
Caveats / open risks
- Disclosure lag is 45-90 days. By the time we see a position, the manager may have already trimmed or exited. v1 accepts this; v2 could add a CUSIP-to-real-time-price layer to detect price moves between filing and our entry that materially change the read.
- Top-10 by dollar value is the wrong proxy in some cases. Berkshire's #1 by dollar (AAPL) has been trimmed substantially. Druckenmiller's top-10 churn is the highest. v1 uses top-10 inclusion as the binary signal; v2 could weight by position-as-%-of-portfolio.
- CUSIP-to-ticker mapping is not yet built. Per the backfill brief, all references use issuer-name strings. The v1 ticker basket is mapped manually (MSFT, AMZN, GOOGL, TSM, SNDK, INTC are unambiguous). Future strategy additions need the CUSIP cache before automation can stretch further.
- Pabrai excluded. The 8th tracked manager (Mohnish Pabrai) failed 13F backfill due to entity-name churn. v1 deploys without his signal; v2 could re-incorporate after the multi-entity CIK lookup is fixed.
- Marathon LLP filings stopped in 2021. The legendary UK capital-cycle firm appears below the $100M 13F threshold. Marathon-style capital-cycle reads via 13F are no longer possible — read Marathon's published 'Global Investment Review' commentary as substitute. Not blocking for v1.
- Berkshire 2025-Q2 returned only 4 positions (likely a 13F-HR/A amendment). The strict period-match logic misses the full Q2 holdings. Documented in the backfill brief; not blocking for v1 selection.
- Persistent-darling category is currently 100% mega-cap tech. No diversification across sector or market cap in the persistent slice. By design — that's where 3+ tracked managers converge — but it concentrates strategy beta into a single factor (AI-infra demand). Acknowledged.
- Overlap with memory-cycle v1.1. SNDK + INTC appear in both strategies' baskets. Position-tracking stays distinct per strategy (each gets its own ledger entry), but founder should be aware that total paper exposure to these two names is the sum across strategies.
Cross-domain translation
The shape here is mechanical mirror trading — also known in the literature as "13F arbitrage" or "smart-money following." Academic studies (Cohen/Polk/Silli 2010, Wermers 2000) showed equal-weighted top-N holdings of skilled active managers can beat passive benchmarks net of lag, but only when (a) the signal source is genuinely skilled, (b) holding period is long enough that the disclosure lag doesn't dominate, and (c) the basket is concentrated enough to capture the signal but diversified enough to survive single-manager error.
v1 satisfies (a) via the 7-manager curation (all positive-sum allocators with public track records). v1 satisfies (b) via the no-price-exit rule (holding period is "until a 2+ manager exit fires," not "until N days"). v1 partially satisfies (c) via the 6-name basket — concentrated enough to express the signal, diversified enough that any single manager's error costs <17% of the strategy.
The Sequoia Fund 2020-2022 analog: Sequoia ran a quarterly-rebalance concentrated portfolio with a similar shape (high-conviction names from a small manager curation, no mechanical price-based exits, quarterly review). The Druckenmiller doctrine ("find the great opportunity, bet heavily, let winners run") is the trading discipline that matches the mirror logic — we're not trying to time within positions, we're trying to ride positions that skilled allocators chose to size up on.
Comparison vs memory-cycle v1.1 (sibling strategy)
| Dimension | memory-cycle v1.1 | smart-money-mirror v1 |
|---|---|---|
| Source of selection | Structural thesis (HBM supply tightness through 2027) | Manager-mirroring (top-N of 7 tracked) |
| Basket size | 4 names (MU, SMH, SNDK, INTC) | 6 names (MSFT, AMZN, GOOGL, TSM, SNDK, INTC) |
| Per-name cap | 3R ($15k) | 1R ($5k) in v1 |
| Bucket cap | 4R ($20k) | 3R initial + $5k reserve (4R = $20k) |
| Exit logic | Anchor-flip founder review; 2+ HIGH severity anchors = close | 2+ manager exit same quarter = close |
| Add logic | Tranche entry + anchor-strength adds | Quarterly rebalance on new 2+ manager additions |
| Review cadence | Quarterly (4-anchor pull) | Quarterly (13F window) |
| Source skill | /investing:build-thesis, /investing:backtest-thesis |
/investing:smart-money-watch |
The two strategies are complementary, not competitive. Memory v1.1 is conviction-sized on a single structural thesis with the option to scale to 3R per name. Smart-money-mirror v1 is diversified across 6 mirror signals with smaller per-name caps and a tighter exit rule. Overlap (SNDK + INTC) is acknowledged; each strategy tracks its own positions.
